GFI MailEssentials for Exchange/SMTP is a server based anti spam and email management solution for Microsoft Exchange Server and Notes/SMTP servers. Spam is caught before it gets to the mail server, no need to deploy client software. Its advanced Spam detection technology is based on: Content checking of body and subject for spam keywords, checking mail headers for typical spam practices, and checking if the sending mail server is on a third part black list such as ORDB. Admins can also set-up their own blacklists, as well as reduce false positives using the automatic whitelist feature. The program also features disclaimers, mail monitoring of particular email addresses, centralized mail archiving to database, mail reporting (e.g., top mail users), POP3 downloading and auto replies with variables/fields. The anti spam DNS blacklists checking (ORDBC etc.), custom blacklist and automatic whitelist modules are freeware and will not time out after evaluation has ended.
